At 100 kilometres north of Brest and not far from the equally famous Perros-Guirec, Ploumanac'h, a former small hamlet inhabited by fishermen, has evolved into one of the most popular resorts on the beautiful Armor coast. The reason? A single pile of pink granite running along 25 hectares of the coast.
The rocks, some of which are 20 metres high, have been polished by sea wind and water for 300 million years, and form an unusual setting between the blue of the sky and the sea. It is especially sublime when the sun sets. To discover the strange forms of this national heritage site, take the Sentier des Douaniers coastal path, which in the course of a half day will take you to the beach of Trestraou, Perros-Guirec, and on to the port of Ploumanac'h. Along the way, visit the oratory of Saint-Guirec and Ploumanac'h lighthouse, both built on blocks of pink granite.
